Lactic acid bacteria: reviewing the potential of a promising delivery live vector for biomedical purposes

Lactic acid bacteria: reviewing the potential of a promising delivery live vector for biomedical purposes

Lactic acid bacteria (LAB) have a long history of safe exploitation by humans, being used for centuries in food production and preservation and as probiotic agents to promote human health. Interestingly, some species of these Gram-positive bacteria, which are generally recognized as safe organisms by the US Food and Drug Administration (FDA), are able to survive through the gastrointestinal tra...

Lactic acid bacteria: a promising alternative for recombinant protein production

Even though the use of Lactic Acid Bacteria (LAB) is well documented for a variety of dairy food fermentation dating back to the earliest written records [1,2], the use of these Gram-positive anaerobic microorganisms as recombinant microbial cell factories has taken place during the last decades. In this context, it is important to note that the enormous potential of these Generally Recognized ...

Lactococcus lactis as a live delivery vector

Mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. Therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. Lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

Lactic acid bacteria as live vaccines.

Mucosal routes for vaccine delivery offer several advantages over systemic inoculation from both immunological and practical points of view. The development of efficient mucosal vaccines therefore represents a top prority in modern vaccinology. One way to deliver protective antigens at the mucosal surfaces is to use live bacterial vectors. Until recently most of these were derived from attenuat...
